Abstract: The present communication system has a communication terminal (100) and a communication terminal (200) that are respectively provided with a memory for writing and reading using error correction coding/decoding. The communication terminal (100) transmits data to the communication terminal (200) in a high speed mode or normal mode. In high speed mode, the communication terminal (100) reads coded data written in a first memory (112) and transmits the coded data to the communication terminal (200) without decoding. The receiving-side communication terminal (200) writes the received data in a second memory (212) without coding, and decodes the data when said data is read.
